Raymond Hill 6acf97bf51 Rewrite cname uncloaking code to account for new `ipaddress=` option ... This commit makes the DNS resolution code better suited for both filtering on cname and ip address. The change allows early availability of ip address so that `ipaddress=` option can be matched at onBeforeRequest time. As a result, it is now possible to block root document using `ipaddress=` option -- so long as an ip address can be extracted before first onBeforeRequest() call. Related issue: https://github.com/uBlockOrigin/uBlock-issues/issues/2792 Caveat ------ the ip address used is the first one among the list of ip addresses returned by dns.resolve() method. There is no way for uBO to know which exact ip address will be used by the browser when sending the request, so this is at most a best guess. The exact IP address used by the browser is available at onHeadersReceived time, and uBO will also filter according to this value, but by then the network request has already been sent to the remote server. Possibly a future improvement would make available the whole list of ip addresses to the filtering engine, but even then it's impossible to know with certainty which ip address will ultimately be used by the browser -- it is entirely possible that the ip address used by the browser might not be in the list received through dns.resolve().		2024-09-12 11:19:57 -04:00
